Halogen Monitor
Operation
Instruction 3015-4584 Rev 9
13
The alarm log shows the type of alarm (LEAK, SPILL, or EVAC), plus the date and time it occurred. If
CLEAR is displayed, this indicates that an alarm was acknowledged at the date and time shown.
Immediately after selecting the
ALARMS
function, the most recent alarm
event is displayed. In the example to the right, record #03 shows that a
Spill Alarm occurred on 06/10/05 at 15:06. Note that if more than 30 alarm
events have occurred, then the newest event overwrites the oldest.
Note that the Alarm Log can be cleared as described in Section
Clearing PPM, ALARMS & FAULTS Data
(page 15).
2.11 System Faults
2.11.1 Functional Overview
If a system malfunction occurs (see Fault Code list, page 14), the front panel
FAULT
light will flash and
the audible alarm, if activated (refer to
AUDALRM
function page 10), will start beeping.
2.11.2 Clearing / Silencing a Fault Alarm
The
FAULT
light and audible alarm will automatically turn OFF after the cause of the fault has been
eliminated.
Pressing the
SILENCE
button while a fault condition still exists causes the internal audible alarm to turn
OFF for a period of time as set by the
SILENCE
function (page 11). The front panel
FAULT
light will
continue to flash, however, as a reminder that a fault condition still exists. The audible-alarm circuit will
reactivate at the end of the silence period if the cause of the fault has not been corrected.
2.11.3 Viewing the Faults Log
From the
Data Display
screen, press any of
the
Keypad
buttons to display the first
Function Menu
screen. Next, use the
Keypad
buttons to move the arrow (>) until it points to the
FAULTS
function, and
then press the
ENTER
button to display the
Faults
Log
screen.
The
Faults Log
screen shows the monitor’s current fault status. If the
fault is still present when the
FAULTS
function is selected, then the
current cause of the fault is displayed along with the date and time it
occurred. If the cause of the fault has been cleared, then the
Faults Log
screen will show <0000> along with the date and time the fault was
cleared. Use the
Keypad
buttons to scroll through the fault log. In the
screens shown to the left, record #03 shows that a Sample Flow Fault
(fault code <0800>) occurred on 07/11/05 at 08:17, while record #04
shows that the fault was cleared on 07/11/05 at 9:00.
The cause of the fault is identified by a numeric fault code. To convert
the fault code into a text description of the fault, first press the
ENTER
button and then use the
Keypad
buttons to scroll through the display
until the text description of the fault appears. If the fault code is a
combination of two or more faults, then continue to use the
Keypad
buttons until all fault text descriptions have been displayed. For example,
the fault code <1800> represents the combination of both a Sample Flow
<0800> and a Purge Flow <1000> fault as shown to the left.
The Fault Log can be cleared as described in
Clearing the PPM, Alarms
and Faults Data
on page 14.
